` ppleation tiled, J'iijly 2,1, 11911 Serial No.. 639,815.

a citizen ofthel United States, residing at Milwaukee, in the county ofMilwaukee and State. of- Wisconsin, have invented certain new and usefulImprovements in Rod-Cub fuse.

ters, of whichy .the following isa specification. lhis inventionrelatesto improvements in rod cutters, the' primary object -of'whichisto provide a machine of this type which is convenient and effective inoperation, and Which will not get out oforderby continuous Other,obje/*cts are 'to :so `arrange the cutting mechanisms that the machinewill'be more powerful as `the resistance increases in ada vancing thecut and sothat the bar to be cut will not, be pushed awaybythe knivesvin the cutting action. v v l.

VStill further objects are toprovide peculiar operating meansas welly asadvantageousv A vented from' `falling throughvby the lower means'tolimit the movement of the jaws.

lilith Ithe aboveand other objects in view, this invention; consistsinthe construction, combination, andA arrangement of parts, rall aslhereinafter more fully described, claimed andfillustrated iii theaccompanying draw'- ings, wherein;l

Figure 1 isv ajside elevation of the rod cutter; Fig. 2'is atop planviewthereof; Fig. 3 is a section on the line 3%3 ofFig. 1; Fig. 4 is aperspective view o'f'one of the jaw members; and'Fig, 'is a` perspective-view of the supporting member.

Throughout the followingdetail description, and `on the several figuresof the drawings,""siniilar partsl are referred to byllike referencecharacters. y v

iRef'errng to the drawings, at 1 is indicated a basev having two pairsof pivot lugs or ears 2 projecting from-the upper surface thereof.Pivoted toone pair of said ears isa jaw 3, and co-acting with said jawis a similar jaw lwhich is pivoted to the other pair of ears 2 by apivot pin 5. Integral with andprojecting rearwardly` from said jawmembers 3 and 4 are lugs 6 which, with -the base member 1, are adaptedto limitthe movement of said ljaw members.

The means for operating the rod cutter consists of a lever 7 which ispivoted at 8 to the jaw member 3 and, which by a link 9, is

connected to the jaw member `4t for simultaneous operation of said jawmember. The link 9 is pivoted by a pin 10 to the lever l` slightly aboveits pivotal connection with 'the jaw member 3 and rests in a groove 11in PATENT orrioia specmeeqnpf tettersrtent. .patented 09u17, 191.1,

the rear portion of a lug 12, ,whichvv latter is'4 integrally carriedbythe aw member L1'. The link 9 which is of U-shaped formationisprovided with -tlie bridge member 13located slightly in front of the lug12 and adapted l to .engage said lu in separating the two jaw members byact-ion of thejle'ver-T.- f I .f The cutting elements consist of knives15 which are mountedin recesses formed inthe jaw members 3/and4 and heldin place by way down, then the cutting kedge projects' studs orbolts/161' Whenthe jawsare in slightly forwardly in a curved linevtoward the opposite cutter member, thereby forming a a` comp.'trativelywidev space between the upper portions ofthe-'knives to permit theentrance of the work', and which Awill be precurved portions of theknivesl.

' The lever 7 is provided with ya socket to receive a handle-17 'adaptedfor'operationl of the cutter, either manually-or byanacliine power.

'To prevent-the rod from bending -in the" .cutting operation thereof, asupport 2O is ad- :justably mounted on the. base of each cutter member.This support is in the form of an angle-.iroi1,and is held in place bythe bolts -16 which, as stated above, are also clamping' Ithe cutters. ly vIn operation, the :handle17 is `operated downwardly, thereby bringingthe jaw menilbers toward each other by action of the link 9, as' clearlyseen vin the drawing, and byV lifting the handle 17, the bridge portion13 will engage with the lug 12, as a result of which the jaw memberswill separate; I t will be noted that the link 9 may be disengaged fromthe lug 12 for convenience in placing the work between the cutters whichis found to be of great advantage when long bars are to'be cut/:v j

To facilitate the operation'of the machine, a .handle 18 is received. ina socket 19 integrally projecting rearwardly from the ljaw member 4.

It will be seen that in the action o f cutting a rod the upper portionofthe knives will be moved toward each other at a greater rate of speedthan the portions which engage .the work, said action resulting in thebar being :1'5 Having thus fully. described invention,-

I prolnptlycaughtbyl the cutters-,thereby pre' venting sidewlse slippingof the bar which 'may occur in an ordinary type'o'f rod cutter.

The construction of this machine is oi pe- 5 culiar advantage'in thataminimum weight..

"same work, 'and therefore this rod cutter is f especially advantageousas a pc .-table toel. as well as in a'machine shop -or manufacturingestablishment. l

whatis claimed as new is-A s l. In a rod cutting machine, thecombination ofa besa-jaws pivotally mounted at their lowerportions onsaid base, a levercar- 0 ried by one 'of said-jaws, anda link pivotedyto said-lever and connected with theother. jaw, whereby *on movement ofthe lever the jaws are lsimultaneously operated.

2. In 'a rod cuttingmachine, the combiv25. nation of a base, pair ofjaws pivoted at their lov r ends to said baseknives carried by saidjaws, a lever pivoted at one end to vthe upper portion ofl one jaw, anda link pv oted at one end tosaid lever and having' 201.115' other endengaged with the other j aw so that on vrfnoveinent of the lever thejaws will be simultaneously forced together.

3. In arod .'Lutting'finachine, the combina- I tion of a base,` a pairof jaws pivoted at their "lower ends to said base, knives" carried bysaid jaws, a lever pivoted at one end to the upper portion of one jaw, alink pivoted at one end to said lever and having its other end engagedwith 'the other jaw so that on l40 movement of the lever the jaws willbe simultaneously forced together, and a bridge -piece connecting thesides of the llnk. and movable against the jaw with which the link ytionof abase, a pair ofjaws pivoted at their lably engaged at oueside by theother end is engaged to separate the jaws aforesaid fn reverse movementof the lever.

4; In a lrod cutting machine, the combinaltion of a base, a pair. ofjaws pivoted at theirlower ends to said base, a lever pivoted at itslower end to one of vthejaws, a link pivotall'y lconnected at one end tothe lever ,and'lhavlng' its yother end detachably yengaged yover theother j aw, so that when the lever is moved in one direction the' vjawswill be simultaneously. forced together, a member Vcarried by -said linkto engage said last mentioned jaw' to separate the Ijaws on reversemovement of .the lever, and knives carried by `'sala jaws.

5. Ina rod cutting machine, the combina` lower ends to the base, a leverpivoted at one end to. one of the jaws, a link of U-form pivotallyconnected at one end toy the lever, a lug carriedA bythe other jaw anddetach-v of lthe link, a lmember connecting the sides of the link andadapted to. engage the opposite sides of thelug to separate the jaws,and knivescarried by the jaws. i

6. In a rod cutting machine, the combination of a pair of jaws, knivescarried by said4 jaws, said knives comprising cutting edges: havingstraight portions adjacent to one end and converging portions at theother ends, said straight portions being substantially parallel when inopen position, and means for actuating vthe knives to cause the stralghtportions to move toward one anotherA faster than the convergingportions.

In testimony whereof ,I aiiix'my signature 80 in presence of twowitnesses.
